Justin Bieber would kick One Direction in the face
The Canadian singer, who's actually rather friendly with the 1D boys, has joked that he wouldn't be afraid to square up to Niall Horan, Zayn Malik, Harry Styles, Louis Tomlinson and Liam Payne - but only if they were alone.
He is quoted as saying: ''I'd get my ass kicked (against all of them). But one-on-one I'd take them. I'd try a spin-kick. To the face.''
Despite Justin's slight build, he'd probably prove quite a force in a fracas.
The boxing fan was recently trained by former world heavyweight champion Mike Tyson, who once bit part off part of his opponent's ear during a bout.
After Justin and Mike's meeting, the retired boxer posted a YouTube video of the 18-year-old pounding his fists into a punch bag.
In a description of the clip on his YouTube page, Mike wrote: ''Justin swung by my place during the weekend of the Billboard Music Awards to say hi to the family. We took him straight to garage and had him hit the bag. JB's got the moves! (sic)''
We're not sure One Direction would prove great competition against Justin - they'd probably rather be playing with their hair in the mirror...or cuddling puppies, apparently.
